Abstract The introduction of glucose oxidase, exhibiting characteristics consumption and H 2 O production, represents an emerging antineoplastic therapeutic approach that disrupts nutrient supply promotes efficient generation reactive oxygen species (ROS). However, the instability natural enzymes their low efficacy significantly impede broader application. In this context, 2D Ca Mn 8 16 nanosheets (CMO NSs) designed engineered to serve as a high‐performance nanozyme, enhancing enzyodynamic effect for ferroptosis–apoptosis synergistic tumor therapy, are presented. addition mimicking activities glutathione peroxidase, catalase, CMO NSs exhibit oxidase‐mimicking activities. This feature contributes antitumor performance through cascade catalytic reactions, involving disruption supply, self‐supply , subsequent ROS generation. exogenous 2+ released from NSs, along with endogenous enrichment induced by peroxidase‐ collectively mediate overload, leading apoptosis. Importantly, ferroptosis process is triggered synchronously output consumption. application ultrasound stimulation further enhances efficiency treatment. work underscores crucial role in therapy against tumors.

Decoding the “Fingerprint” of Implant Materials: Insights into the Foreign Body Reaction

Small, Год журнала: 2024, Номер 20(23)

Опубликована: Янв. 8, 2024

Abstract Foreign body reaction (FBR) is a prevalent yet often overlooked pathological phenomenon, particularly within the field of biomedical implantation. The presence FBR poses heavy burden on both medical and socioeconomic systems. This review seeks to elucidate protein “fingerprint” implant materials, which generated by physiochemical properties materials themselves. In this review, activity macrophages, formation foreign giant cells (FBGCs), development fibrosis capsules in context are introduced. Additionally, relationship between various elucidated detail, as an overview existing approaches technologies employed alleviate FBR. Finally, significance components (metallic non‐metallic materials), surface CHEMISTRY (charge wettability), physical characteristics (topography, roughness, stiffness) establishing also well documented. conclusion, aims emphasize importance provides current perspectives developing with anti‐FBR properties.

Understanding the Novel Approach of Nanoferroptosis for Cancer Therapy

Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Май 2, 2024

As a new form of regulated cell death, ferroptosis has unraveled the unsolicited theory intrinsic apoptosis resistance by cancer cells. The molecular mechanism depends on induction oxidative stress through excessive reactive oxygen species accumulation and glutathione depletion to damage structural integrity Due their high loading tunability, nanocarriers can escort delivery ferro-therapeutics desired site enhanced permeation or retention effect active targeting. This review shed light necessity iron in growth fascinating features regulating cycle metastasis. Additionally, we discussed ferroptosis-mediated therapy using nanoplatforms chemical basis overcoming barriers therapy.

Ferroptosis is a type of iron-dependent programmed cell death characterized by depletion glutathione. Although generally less harmful to normal cells, in tumor the high demand for iron ions provides conditions conducive ferroptosis. In this review, we provide an overview recent progress research on regulation ferroptosis summarizing and assessing current state, trends, applications nanomaterials cells. Given advantages terms targeting, safety, improved drug efficacy, reduced side effects, these materials are considered have potential therapeutic value modulating cells via different mechanisms. respect, describe methods modifying interfering with glutathione activity lipid peroxidation. The development that can be applied induce or inhibit anticipated new options treatment diverse range diseases.

“Mix‐and‐Match”: Self‐Sorting Assembly Governed Supramolecular Polymeric Nanomedicine for Boosting Combined Chemo/Phototherapy

Advanced Materials, Год журнала: 2025, Номер unknown

Abstract Precise cancer nanomedicine requires rational molecular instructions of therapeutic agents. Harnessing the structure‐property‐function relationships represents a practical strategy toward smart and effective nanomedicine. A structurally novel hydrogen‐bonded (H‐bonded) supramolecular nanoformulation generated by orthogonal self‐sorting assembly chemo‐prodrug (FPtF) phototherapeutics (BPeB) is here reported, to reach an autonomous with improved anti‐tumor efficacy combining chemo/phototherapy (CT/PT). The high‐fidelity H‐bonding modularity from privileged heterocomplementary diaminopyridine/5‐fluorouracil (DAP/FU) Hamilton wedge/barbiturate (HW/Ba) pairs, respectively enable precise spatial control binding interactions FPtF BPeB, in turn allowing process specific “mix‐and‐match” capability. To directly stimulate phototherapy BPeB via near‐infrared (NIR) light, spectral matched upconversion nanoparticles (UCNPs, β‐NaYF 4 :Yb,Er) are encapsulated simultaneously. As result, polymeric nanomicelles, i.e., F/B/U@PHDO, readily fabricated. Moreover, distinct association constant (Ka) DAP/FU (≈10 2 M −1 ) HW/Ba 4‐5 pairs reflect different strengths stabilities H‐bonds, thus endowing programmable dissociation, accompanied release through pH/thermal‐stimuli. Therapeutic regime appreciated outcomes ultimately accomplished combined CT/PT. opportunities offered design anticipated point new paradigm for therapy.
